As there are many manufacturers offering sofa beds, you will notice great differences both in quality and pricing. Needless to say, buy the best quality you can afford. Often sleepers in higher price points are also better made. If you have a very small space then Twin size sofa beds might be the perfect answer for you as these are less than 5 feet wide and they are great for sleeping one person. The mattress for a twin size sleeper sofa is about 39" wide.

When hanging anything above a sofa, keep in mind that the number one mistake people make is to hang something that´s too small. The piece, whatever it may be, should generally be about two-thirds the width of the sofa (unless you´re opting for something purposely over-scale). If you‘re hanging a group of pieces the same rule generally applies. Other than that the rules are pretty loose, so be creative and choose something that speaks to you and makes you smile.

A queen size sleeper sofa can easily seat three, and can provide a comfortable bed for two people. It will measure approximately 84 inches wide and be about 90 inches long when the bed is opened up. If the sleeper is going to be used every night for sleeping, a full-size sleeper sofa is what you need even if you have a tiny space. An adult might find a twin-sized sleeper too small and restricting for everyday use, and, in a pinch, a full-size sleeper can even sleep two. But again if two people are going to use it regularly, the full sized sleeper might not be very comfortable or spacious enough.
